2 Claims. (01. 215-42) This invention relates to closures fornonrefillable bottles or other containers, and it has for its object toprovide an improved closure that will allow the free passage of thecontents therefrom but will prevent refillingafter the contents of thecontainer is exhausted,

Another object of the invention is to provide a closure fornon-refillable bottles or other containers, that can be easily andexpeditiously secured to the bottle or container, which cannot beremoved therefrom without breaking or .damaging the means permanentlysecuring the closure to the bottle or container.

A further object of the invention is to provide a. closure fornon-refillable bottles or containers, that will guarantee thegenuineness of the contents thereof and retain same free fromcontamination until completely exhausted, which is neat and simple inconstruction, inexpensive to manufacture by reason of the minimum of theelements composing same, and perfectly efficient in operation.

This invention will be described with reference to the figures of theaccompanying drawings, of which:

Fig. 1 is a diametral vertical section view of the closure applied to abottle neck in upright position.

Fig. 2 is a view similar to Fig. 1, showing the bottle neck inverted forpouring the contents therefrom and through the closure.

Fig. 3 is a sectional view taken on the line AA of Fig. 1.

Fig. 4 is a top plan View of the loose valve operating within theclosure.

Fig. 5 is an elevation of the valve. 7

Fig. '6 is an elevation of the disc which forms a seat for thesemi-spherical lower portion of the valve.

Fig. 71s a dimetral sectional view of the closure applied to a bottleneck in horizontal position.

In the drawings, the numeral l indicates the neck of a bottle whereinthere is inserted a hollow cylindrical body 2 which may be formed fromglass or a plastic material and which has its lower end open andprovided with inner threads 3 and its upper end 4 closed and of adiameter slightly greater than that of the lower open end. Said'upperend 4 is provided at its outer surface about its line of greaterdiameter with relation to the rest of the body 2, with an annular flange5 upon which is disposed an apertured rubber washer 6 upon which isfitted a metallic cap 22 which permanently secures the closure to thebottle neck and beneath said annular flange 5 there is provided anotherannula apertured washer I through which said annular flange 5 seats uponthe mouth or upper end of the bottle. Said upper end 4 has at the middleportion of its outer side surface a flattened area having centrallyarranged thereon an opening 8 and an exteriorly threaded nipple adaptedto. act as an outlet for the contents of the bottle.

Said hollow cylindrical body 2 is tapered from opening 8 to a point nearits lower open end'and. has formed at a certain height of its inner wallinter-spaced tooth-shaped projections 9 adapted to serve as stops for apellet In which is prefersably formed from glass or metal or analcohol-a proof material. Said pellet I0 is loosely disposed betweensaid projections 9 and the top portion of a valve H which is looselyinserted within the lower threaded end of cylindrical body 2. On theinnerly threaded lower open end of body 2 there is screwed an innerlyconical disc 12 which is reduced in half of its lower surface and hascontrally formed on its upper surface an outerly threaded nipple 21having its upper edge burnished to a semi-spherical contour said nipple2| being adapted to act as a seat for the valve H.

The lower open end of body 2 has formed in its inner wall and near itsedge an annular recess [4 having formed therewith four inter-spacedtooth-shaped projections l5 and above said annular recess [.4 there aresuitably formed four other inter-spaced tooth-spaced projections IB,allsaid projections serving to guide the valve II in its movement withinthe lower open end of body 2.

The closed end 4 of body 2 has formed in its side opposite the liquidoutlet opening 8 an air inlet opening 13 extending vertically within thewall of body 2 and ending in the annular re cess I4.

The valve ll consists of a burnished cylindrical member having its topportion open and its bottom portion closed in. a semi-spherical shapehaving centrally formed therein a hole and arranged thereon an outernipple 11, said valve having laterally formed therein two opposed squareopenings I9, Within the semi-spherical end of valve ll there is disposedat piece'of cork Or other floatable material l8 whose upper edge reachesnear the upper edges of openings I9 the cork or other floatable materialbeing recessed at its edges, such recesses or slots coinciding with saidupper ends of openings I9, so that liquid may flow through the openingsl9. into the inte rior oi the valve body II. as will be more specifissally pointed out and described hereinafter.

In the top open end of valve I I there is pressure fitted a rectangularmember 20 which is adapted to serve as a stop for the cork piece I8 andalso as a seat for the pellet I0, said rectangular member 20 having asmall perforation at the middle portion of its upper surface.

The closure of this invention is secured to the neck of the container bymeans of an annular metallic cap 22 having centrally formed in its upperplane surface an opening through which protrudes upwardly the upper endof body 2, the

side edges of said cap being of a suitable length so that pressure onsaid side edges will cause same to be tight against and beneath theouter flange of the bottle neck I. v

The operation of this closure is as follows:

' ings and with an annular recess interiorly of its When it is desiredto pour the contents of the j container, it is tilted from its: uprightposition to the position shown in Fig. 2. When so arranged the airentering through air inlet I3 will allow the contents to pass freelythrough the central opening of the disc I2 into the annular recess l4through the spaces provided by the projections I5, whereupon the liquidwill displace the valve I I onward at the same time that the pellet I0drops on the projections 9. The liquid then flows through the opposedlateral square apertures I9 of the valve I I and through the twoopenings into which the upper open end of the valve I I is divided bythe rectangular piece fitted therein, and the liquid also flows in asmaller amount through the spaces provided between the projections I6.Finally the liquid passes through the spaces between the projections 9and the remaining portion of the body 2, to find its way out through thedischarge outlet 8 It is evident that an attempt to inject liquid intothe bottle through outlet nipple 8 of the closure in the normal orupright position of the bottle will be futile, by reasonof the fact thatthe valve II, with the aid of the weight of pellet Ill which normallyrests on the top portion of the valve, will normally rest on theburnished edge of the nipple of disc I2 wherethrough the liquid to bepoured enters into the closure, and the pressure exerted by the liquidbeing injected into the closure will force the valve I I on its seat andthe pellet I0 upon the valve, whereupon the liquid upon being preventedfrom passing down into the bottle will tend to find its way out throughair inlet'opening'l3. "Similarly, liquid cannot be injected into theclosure in the horizontal'position of the bottle as shown in Fig. '7,due to the fact that by reason of the conical shape of the inner wall ofthe body 2, the pellet Ill normally tends to run to its resting positionon the valve I I and to force the valve I I on its seat formed 'on thedisc I2 wherethrough the liquid to be discharged flows into the closure,whereupon the liquid will be prevented from flowinginto the bottle andwill find its way out through the'a ir inlet opening I3.

' If an attempt should be made to force liquid into the closure in thetilted position of the bottle shown in Fig. 2, the valve, due tothefloating nature of the cork enclosed therein,'will ascend as the liquidenters into the closure, until it fits against the disc I2 whichnormally acts as the valve seat, whereby the liquid will be preventedfrom entering into the bottle and compelled to find its way out throughair inlet opening I3.

It is evident that in any position of the bottle, if an attempt shouldbe made to inject liquid into the closure by obturating either the airinlet or the liquid discharge openings, the very pressure lower end, ametallic cap that inviolably secures said hollow cylindrical body to theupper end of the container through a washer, a cylindrical valve looselydisposed within said hollow cylindrical body and slidable therein, andwhich is open above and closed below and ends in a semispherical portionhaving centrally arranged therein and formed therewith an outer nipple,a portion of a fioatable material disposed within said semi-sphericalportion of the valve, guiding means for said valve in its movementwithin said hollow cylindrical body, a seat for said valve, a pelletloosely disposed within said hollow cylindrical body and adapted tonormally rest on the top of said valve, and means for limiting the runof said pellet within said hollow cylindrical body.
